Velcro Strap Bracket for Mini Kraton

Arrma Mini Kraton Velcro Strap Battery Bracket Set (Metal or Plastic)

This Velcro Strap Battery Bracket replaces the factory battery tray arm on the Arrma Mini Kraton and solves a common problem: aftermarket batteries that are too large for the stock tray to close.

Instead of being locked into one battery size, this system lets you secure your battery with a Velcro strap, giving you real adjustability and flexibility.

Both Metal and Plastic versions are available, and each version includes a standard Velcro strap for secure battery retention.

Plastic Version (ASA+)

The plastic version is sold as a complete set and includes:

• Small bracket – Allows fitment of the largest batteries possible
• Large bracket – Provides additional downward pressure for smaller batteries that need to be held more securely

Each bracket is 3D printed using ASA+ filament, offering major advantages over standard PLA:

• Higher heat resistance (won’t soften or deform in hot conditions)
• Better impact resistance
• Superior durability for outdoor use

Metal Version - Laser Cut 7075-T6 Aluminum 

The metal version is precision Laser-cut for precise fit and a premium upgrade look.

Benefits include:

• Maximum durability for extreme bashing
• Increased rigidity with zero flex
• Long-term wear resistance
• Clean, high-end appearance
• Threaded M2.5 hole
• Uses factory M2.5x12mm screw

What This System Does

This setup gives you the freedom to run a wide range of battery sizes while keeping everything tight and secure during hard bashing.

Included with each set:

• Heavy-duty Velcro battery strap
• 2.5mm x 20mm machined socket head screw for secure installation

Key Features
